Daily Mail, UK - Vowing to turn away immigrants and run America like his own glittering business empire, Donald Trump has become the frontrunner for the Republican presidential nomination.
But he has been less vocal about the root of his success: a chain of seedy brothels and restaurants setup by his immigrant grandfather Friedrich Drumpf.
Born in Germany, Friedrich took a boat to New York City at the age of 16 in 1885 to join his older sister and find work.
The move sent him on a wild journey across America into the brothel industry of the Wild West, making him a fortune - and allowing him to dodge army service and taxes back home in Germany.
In fact, he even tried to return home to Kallstadt to marry his neighbor sweetheart and settle down with his wealth, according to German history books. But he was refused repatriation and was forced back to New York to start a family - and ultimately raise a likely contender for the presidency.
